High-flexibility machining system and method based on milling-milling combined machining principle

Abstract

The invention discloses a high-flexibility machining system and method based on the milling-milling combined machining principle. The high-flexibility machining system based on the milling-milling combined machining principle comprises a supporting feeding mechanism, a control mechanism, an auxiliary machining mechanism and a power head mechanism. The supporting feeding mechanism adopts an industrial robot. A power head is installed at the tail end of a mechanical arm through an adapter plate. The auxiliary machining mechanism comprises an indexable workbench. A workpiece to be machined is placed on the indexable workbench. The industrial robot, the indexable workbench and the power head mechanism are in signal connection with a numerical control module in the control mechanism. Multiple end mills are fixed to a cutter head of the power head and evenly distributed in the circumferential direction. Each end mill rotates around the axis of the cutter head and also rotates around own axisat the same time. The rotation directions of every two adjacent planetary end mills are opposite. The high-flexibility machining system and method based on the milling-milling combined machining principle have the advantages that the cutting force is small, the cutting temperature is low, cutting vibration is small, the wear of cutters is little, the service lives of the cutters are long, and themachining efficiency is high.

Description

technical field [0001] The invention relates to the technical field of cutting processing, in particular to a highly flexible processing system and processing method based on the principle of milling-milling compound processing. Background technique [0002] Existing milling processing includes turning-milling composite processing and large-scale gantry milling machine processing. The turning-milling compound processing machine tool is mainly composed of a spindle system, a power tool holder, a feed system, a bed and auxiliary systems such as a numerical control system, a hydraulic and pneumatic system, and a cooling system. The spindle system is mainly used to drive the workpiece to perform rotary motion, the power tool post is mainly used to drive the rotary tool for cutting motion or clamp the indexable insert for feeding motion, and the main function of the auxiliary system is to perform processing control, cooling and lubrication, etc. Turn-milling combined machining i...

Problems solved by technology

If the helical edge end mill is used for large plane milling, the milling efficiency will be low due to its small cutting area

[0004] Most of the existing equipment for large plane milling is the above-mentioned large gantry milling machine. There are many shortcomings when using this machine tool for large plane milling of difficult-to-machine materials, as follows: (1) The cutting force is large during the processing (2) Severe tool wear (3) Low processing efficiency (4) Limited processing size range and poor flexibility
